Method Detail

dimension

public abstract int dimension(int jfin)

dimension

public abstract int dimension()

clone

public java.lang.Object clone()

Return a copy of the object

toString

public abstract java.lang.String toString()

Return a string representing the object

evaluate

public abstract double[] evaluate(int j1)

Return as an array the sampled values of the function

mass

public double mass(double a,
                   double b,
                   int jfin)

Compute the mass (integral)

Parameters:

a - left boundary of the interval

b - right boundary of the interval

jfin - number of iterations to consider (precision)

mass

public double mass(int jfin)

Compute the mass (integral) of the interval 0,1

Parameters:

jfin - number of iterations to consider (precision)

getFilterType

public abstract int getFilterType()

This method is used to compute how the number of scaling functions changes from on scale to the other. Basically, if you have k scaling function and a Filter of type t, you'll have 2*k+t scaling functions at the next scale (dyadic case). Notice that this method assumes that one is working with the dyadic grid while the method "previousDimension" define in the interface "Filter" doesn't.

equals

public abstract boolean equals(java.lang.Object o)

Check if another object is equal to this MultiscaleFunction object
